Specification forming part of Letters Patent No.138,616, dated May 6, 1873; applica March 22, 1873. l v

To all whom it may concern:

Be it known that I, R0121. W. COFFEE, of Big Spring, in the county of Montgomery and State of Virginia, have invented an Improvement in Spoke-Machines; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which Figure l is a perspective view Fig. 2, an elevation of one end, and Fig. 3 an elevation of the other end, of the machine.

Similar letters of reference in the accompanying drawing denote the same parts.

This invention has for its object to improve the construction of machines for turning spokes in such a manner as to provide an apparatus by which the carriage containing the cutter-head and bits can'be made to reciprocate along the spoke, which is held between chucks, for the purpose of cutting the spoke to the proper shape, and by which the carriage containing the spoke and pattern is made to vibrate, and the pattern kept pressed against the rest, which serves as a shapinggage. To this end the invention consists in the construction and combination of parts, which I will now proceed to describe.

In the accompanying drawing, Ais the cutter-head, the same containing the bits by which the spoke is cut, and placed on a shaft, B, which is rotated by means of a belt 0, running over a wheel, B, on the shaft B, and also over the driving-drum D. E E are the chucks which hold the spoke, the chuck E being stationary and the chuck E rotary through the agency of gears E E mounted in the recessed end piece F of the carriage F, the gear E having a wheel, E on its shaft,

which wheel is connected by a belt, G, with a fusee, G, mounted on the end of the machine-frame beneath, and connected by a belt, H, with another fusee, H, on the end of the shaft of the drum D. The gear E is connected with a gear, E in the same recess, which gear turns the pattern I. The carriage F slides on guides F on each of which is a spiral spring, F which springs bear on the carriage F, and keep the pattern I pressed against the rest I, which serves as a shapinggage, and is rigidly fastened to the frame J PATENT OF ICE.

on filed that carries the'cutter-shaft B. rom this it will be seen that when the drum D is turned by the application of any suita power the cutter shaft and head and. the ttern I are also turned. A band, J ,-fastcne to one end of the frame J, runs thence over isheave, J thence to and around a shaft, 1 mounted across the end of the machine-fr e thence back to and over a sheave, J the other end of the machine-frame, and t ence to the adjacent end of the frame J. he shaft K has a gear, K at or near'its n ddle, and a gear, K at one end. Beneath e shaft K, and mounted in the same posts 1 ;L', is a parallel shaft, M, having on it a belt heel, M a gear, M and at one end a gear, adjacent to the gear K A belt, N, conne s'the wheel M with a wheel, N, on the en of a shaft which extends lengthwise of th frame, and bears on its other end the fusee lj hence the shaft M turns when the drum D i urns. O is a lever pivoted to the projectin 1 end of the plate X of the machine-frame, an O a catch with two notches. The shaft v is movable endwise by means of the lever O.

Suppose the cutter-head A in l he position shown in Fig. 1, and you wish to I et it in motion toward the right in order to q t'the spoke held between the chucks E E pr ss the head of the lever 0 against the end of 1 he shaft K until theupper notch of the catc 0 falls behind said lever and fastens it, t spring K acting in opposition and keepii the shaft steady. This movement brings 1 e gears K and M into connection, and the fore draws the frame J to the right through he medium of the shaft K and band J The utter-head A having by the continuation o said-movement reached the end of the spol raise the catch 0. This allows the spring 1 3 to throw the shaft K backward until the ear K en gages with a gear, P, mounted on he outside of the post L, and turned by t e gear M". The gear 1? reverses the motion the shaft K, and the frame J therefore mov in the opposite direction, traveling along t e spoke toward the chuck E, and finishing r e spoke as it goes. A new spoke is then t into the chuck, and the operation renewe WVhenever it is desired to stop i e frame J, the lower notch of O is set behi d the lever 0, and this disconnects the shafts K and M 2. The combination of the carriages F, patcompletely. tern I, guides F springs F rest 1, frame J, I claim as my invention and cutter-head A, all constructed and ar- 1. The combination of the drum D, fusees ranged to operate substantially as specified.
